Abstract (en)
Silicon carbide fibers having a high mechanical strength at a high temperature, an excellent heat resistance and a uniform structure are produced by bringing porous carbon fibers preferably having a specific surface area of 100 to 3,000 m<2>/g into contact with a silicon monoxide gas at a temperature of 800 DEG C to 2,000 DEG C preferably under a reduced pressure or in an inert gas atmosphere, and optionally the resultant silicon carbide fibers are heat-treated at a temperature of 800 DEG C to 2,000 DEG C in the presence of an oxidative gas.
